Description
A heterogeneous Geographical Information System (GIS) was developed to analyze fish distribution and abundance patterns on the Agulhas Bank, South Africa. The sparid fish, Pterogymnus laniarius, was chosen as a candidate species for analysis because of its commercial importance and high biomass. The results using Generalized Additive Modeling within the GIS revealed that there was a nursery area for immature fish on the central Agulhas Bank. After sexual maturation, approximately 40% of the biomass migrated eastward, colonizing large areas of the eastern Agulhas Bank. The use of GIS methodologies in integrated fishery management is discussed as it appears to be a developing trend in analyzing fish distribution and abundance data.
